Abstract
The utility model provides a spiral spring type cushioning device which can enable the rebound load of the shock absorber to meet the requirement when the shock absorber is in different states. The cushioning device in the vehicle shock absorber comprises a spiral spring, the cross section of which is rectangular. Because the buffer spring with rectangular cross section is adopted, the structure is compact, the variable rigidity characteristic of the spring is good, sufficient spring characteristic can be provided in a limited space, and the energy absorbing capacity is high, so as to meet the functional requirement on the shock absorber during high-speed rebound; the reliability and the durability are good, which can meet the application requirement of the shock absorber; the structure is easy to adjust in a limited space, the cost is low, the manufacturing process is simple, the effect is good, therefore, the cushioning device is suitable to be used on different types of vehicle shock absorbers.
Description
Technical field
The utility model relates to a kind of damping device, particularly relates to the damping device of a kind of automobile absorber inside.
Background technique
Be applied to the damping device on the piston rod assembly of automobile absorber inside at present, rigidity contact and collision when its effect mainly is effective buffer high speed resilience between adjacent two metal partss, to avoid the vibration damper disabler, it mainly contains two kinds of structural types, and a kind of is the cylindrically coiled spring formula damping device 1 of metal, as shown in Figure 1, the cross section of cylindrically coiled spring 1 is circular, limited by the vibration damper inner space, its spring performance and resilience cushion effect are little, are mainly used in Light-duty Vehicle; Another kind is nonmetal cushion pad 2, and as shown in Figure 2, cushion pad 2 is generally materials such as polyurethane or rubber, and the buffering spring-back force is big under the ultimate state, but shortcoming is easy inefficacy, aging, life-span weak point.
The model utility content
Technical problem to be solved in the utility model provides a kind of damping device of helical spring type, can make vibration damper under different conditions, and the resilience load all meets the demands.
The technological scheme that the utility model technical solution problem is adopted is: the damping device of automobile absorber inside, comprise helical spring, and described helical spring cross section is a rectangle.
The beneficial effects of the utility model are: owing to adopt the damping spring of rectangular cross-section, compact structure, it is good that spring becomes stiffness characteristics, can have enough spring performances in the confined space, higher energy absorption capability, the functional requirement when satisfying the resilience of vibration damper high speed; Reliability, endurance quality better satisfy the vibration damper usage requirement, and its structure is adjusted in the confined space easily, and cost is low, and manufacturing process is simple, and is respond well, is suitable for using on dissimilar vehicular shock absorbers.
Description of drawings
Fig. 1 is the use sectional drawing of existing cylindrically coiled spring formula damping device.
Fig. 2 is the use sectional drawing of existing cushion pad.
Fig. 3 is the use sectional drawing of damping device of the present utility model.
Embodiment
Fig. 1 is the use sectional drawing of existing cylindrically coiled spring formula damping device, and its spring performance is linear, and elastic force is little, and spring rate limits by the vibration damper space, and raising is not got on.Fig. 2 is the use sectional drawing of existing cushion pad, and the cushion pad material is nonmetallic polyurethane or rubber, and spring performance is non-linear, elastic force height, shape are subjected to the vibration damper spatial constraints, and short transverse is difficult for excessive, be generally the 6-15 millimeter, aging easily, distortion, even come off, fall slag, influence the vibration damper turbidity test, bigger variation easily takes place in radial dimension in addition, thereby block the vibration damper space, it is not smooth to cause damping fluid to flow, and influences the vibration damper proper functioning.
Fig. 3 is the use sectional drawing of damping device of the present utility model, and damping device changes rectangular coil spring 3 into by existing cylindrically coiled spring, that is to say, changes the helical spring that cross section is a rectangle into by the helical spring of existing cylindrical cross-section.Piston rod 9, rectangular coil spring 3, retaining ring 4, piston 6 are formed the piston lever of reducer assembly, and are assemblied in work in the clutch release slave cylinder 5, in the clutch release slave cylinder 5 damping fluid are arranged.Guide holder 10 links together with clutch release slave cylinder 5, and piston 6 is divided into epicoele and cavity of resorption with clutch release slave cylinder 5, and rectangle damping spring 3 is operated in the epicoele.Rectangular coil spring 3 is installed on the piston rod 9 by the endoporus Spielpassung, and its underpart and retaining ring 4 are connected and fixed, and retaining ring 4 is riveted with piston rod or welded together.When piston rod 9 makes progress high speed resilience campaign, rectangular coil spring 3 will with guide holder 10 contact-impacts, at this moment but rectangular coil spring 3 can be vibration damper safety bearing load with the dilution of vibration damper enormous impact load buffer, thereby avoids rigid impulse to damage Shock Absorber.Therefore the performance of rectangular coil spring 3 will determine Security, the reliability of vibration damper.
The characteristic of rectangular coil spring 3 of the present utility model increases with respect to the cylindrically coiled spring amount of deformation for becoming stiffness characteristics, thereby its recoil of spring stroke is increased.Can be according to the resilience payload, camber of spring presents different the variation, avoided damping spring under the vibration damper maximal work state through normal pressure and extreme case the reliability and the life-span of having improved vibration damper appear.
The spring performance of rectangular coil spring 3 of the present utility model is non-linear, the elasticity rate cylindrically coiled spring is big more than 30%, the relative round wire Economy of material is better, it is bigger than cylindrically coiled spring to adjust the space on the structure, though and compare spring performance with cushion pad big less than cushion pad, reliability and good endurance.Therefore, the rectangular coil spring is compared with cushion pad with cylindrically coiled spring, spring performance, reliability, durability and stable aspect have better advantage.
